Is oxygen always a good thing?

When it comes to water treatment, the answer might surprise you. While oxygen is vital for life, dissolved oxygen (DO) in water can actually cause corrosion, bacterial growth, and contamination in sensitive systems. That’s where nitrogen gas comes in.

In this article, we’ll explore how nitrogen sparging works, why removing dissolved oxygen is critical for water quality, and how our advanced Nitrogen Generation Systems—including our newly launched high-flow MNG Series units—deliver reliable performance for modern water treatment applications.

Why Dissolved Oxygen Can Be a Problem

Dissolved oxygen, though naturally present in water, can lead to significant challenges in various industries—from power generation to pharmaceuticals and food production. High DO levels accelerate corrosion in metal piping, promote the growth of aerobic bacteria, and degrade water quality.

By removing oxygen from process water, facilities can extend the life of their equipment, reduce maintenance costs, and ensure a cleaner, more stable system environment.

The Science Behind Nitrogen Sparging

Nitrogen sparging (or nitrogen stripping) is a process that uses nitrogen gas to displace dissolved oxygen in liquids. When nitrogen is introduced into the water stream, it forms fine bubbles that strip oxygen molecules out of the solution. The result? Water with minimal oxygen content—ideal for industrial applications that demand purity and stability.

This process is not only efficient but also environmentally friendly, since nitrogen makes up 78% of the air we breathe. With the right Nitrogen Generation System, facilities can produce nitrogen on-site safely, eliminating the need for costly gas deliveries and storage.

Introducing CGT’s New High-Flow MNG Series Nitrogen Generation System

As part of our ongoing innovation, CGT is proud to announce the launch of our new High-Flow MNG Series Nitrogen Generation Systems, designed specifically for applications requiring increased gas capacity without compromising efficiency or purity.

Our MNG Series membrane units offer:

• High-flow performance for demanding industrial processes
• Compact, low-maintenance design ideal for continuous operation
• On-site nitrogen generation that reduces long-term costs and environmental impact

Whether used for water treatment, food packaging, or industrial inerting, these systems provide reliable nitrogen production tailored to your operation’s needs.

The Benefits of On-Site Nitrogen Generation for Water Treatment

Switching to an on-site Nitrogen Generation System offers significant advantages:

• Improved water quality through consistent oxygen removal
• Reduced operating costs compared to bulk nitrogen deliveries
• Greater reliability with continuous, on-demand nitrogen supply
• Smaller carbon footprint thanks to sustainable membrane technology

With our systems, you can take full control of their nitrogen production and eliminate the variability and expense of outsourced gas supply.
